T. Arioli et al. performed a "molecular analysis of cellulose biosynthesis in Arabidopsis" (wall cress plant) with the use of an "rsw1 mutant [gene with a] temperature-sensitive allele [that] is changed in one amino acid" (Reports, 30 Jan., p. 717).

R. H. Atalla comments that the results, while "an important contribution," do not rule out "two alternative interpretations of the soluble b-1,4-linked glucan" that accumulates in the presence of the mutant rsw1 gene. He states that "careful permethylation analyses ... will be important to the full development of the implications of the observations made by Arioli et al."The full text of these comments can be seen at www.sciencemag.org/cgi/content/full/282/5389/591a
